This invention has reference to generators for the production of water-gas, producer gas, or the like provided with rotary grate structures designed to effect mechanical clinkering of the fuel-beds and more especiall to such generators as have water-sealed grate structures.

According to the invention the rotary grate 'structure of a mechanically clinkered generator is supported by annular surfaces resting one upon another and forming a gas? tight sliding joint adapted to prevent escape or short circuiting of a'ir, steam or gas. These surfaces may be the lower and upper surfaces of a ringformed on or attached to the underside of the grate structure and a lixed ring respectively, one of which may be formed with a lange to serve as a guide to prevent lateral displacement of the grate structure.

While more especially applicable to water sealed gas generators, this invention may be advantageously applied to completely enclosed mechanically clinkered generators for better support and guidance of the rotating portion and to prevent the short-circuiting of the grat-e proper by air and steam, and also down-run gas in the case of water-gas generators, which short circuiting not only carries dust and ashes to the driving gear and journals, but, in the case of water gas-generators,- encourages undesirable combustion near the bottom which leads todamage to the lower parts of the generator.

In the accompanying drawings:

Figure 1 shows in vertical section the lower part of a self-clinkering water-gas generator of the kind in which the rotary grate, supported by annular surfaces according to the present invention, is formed with an outer water seal through which the clinker is continuously discharged to the atmosphere. Figure 2 is a similar view illustrating the present invention applied to a/ completely en'- closed selffclinkering generator of the kind in which there is a dry seal.

Referring to Figure 1, a is an annular water jacket surrounding the lower portion of the fuel bed and theinner wall of which forms part of the generator wall surrounding a gas generating' chamber b. is a rotary 98,142, and in Great Britain May 6, 1925.

bottom or base plate carrying a. cylinder or drum g1 set eccentrically and having a conical cover or upper portion g formed with air passages. The bottom h also carries an annular wall k1 forming between it and the cylinder or drum g1 a water seal trough into which de- Lthe lower edge of the generator wall, a gastight sliding joint around nthe conduit la; preferably the underside of the rotary base plate L is formed or provided with a ring 10` and a A ring 11 vis carried by a fixed supporting wall or foundation 12, the lower and upper surfaces of the rings l0 and 11 resting one on the other and forming the as-tight sliding joint and also serving asthe caring surfaces which evenly -support the entire grate structure and superimposed fuel-bed. Conduit c lserves to admit air to the 'gas generating chamber b and also has steam inlet means s thereon. One of the rings 10 or 11 may be formed with alange which overlaps internally or externally the other andse-rves asa guide to prevent lateral displacement of the rotating grate structure; in the drawings the lower ring 11 is shown with an external flange 11. Other guiding means may be employed. Suitable'provision is made for supplying'a lubricant to the bearing surfaces which facilitates them slidin `one over the other and tends to ensure tig tness of the joint; usually the fixed ring 11 will be. flanged externally as referred to and of channel section so as to retain the lubricant. The rings 10 and 11 may be of diierent metals and either or both may be provided with renewable wearing surfaces. l

'Between the fixed ring. 11 and the conduit 7c a floor 14 is provided to whichA the said conduit is connected, The conduit k may be extended upwardly through this floor above the level of the sliding joint.

- The annular chamber thus formed may be charged with Water or other liquid or lubricant to above the level of the sliding joint. When liquid is employed, a supply pipe l5 and an overflow pipe 16 may be provided. By thus charging the annular chamber, gas and steam are kept from Contact with the joint and from possible leakage to the atmosphere, the accumulation of a dangerous explosive mixture within this almost closed chamber is obviated, dust is prevented from reaching the joint, and the lubrication of the joint is ensured or improved. rllhe mouth of the conduit 7c is overlapped by an annular plate 17 attached to the bottom 7i around its opening so that ashes falling through the grate will be directed into said conduit. i

rlhe arrangement comprising a sliding annular metal joint not only provides a positive inner seal requiringbut little space vertically, but also takes the heavy weight and side thrust.

In Figure 2, Which represents a self-elinkering generator having a dry seal the improvements hereinbefore described with reference to Figure 1 of the accompanying drawings are embodied and the same reference letters and numerals are applied to similar parts.

It will be obvious to those skilled in the art to which the invention relates that modifi- I cations may be made in details of construction `lar surfaces supporting said rotary grate structure and resting in contact one upon another, the lower and upper surfaces consisting of av ring provided on the grate structure'and a fixed ring respectively and one of said rings provided with a flange which overlaps the other ring.
